CONVEYEB-CHUTE.

Specification of Letters Patent.

Patented @ct. 12, 192.

Application filed June 20, 1916. Serial No. 104,762.

To all 212710121 it may concern.

Be it known that I, THEUPHILUS BRowN, a citizen of the United States,residing at Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in Conveyer- Chutes.of which the following is a specification, reference being had thereinto the accompanying drawing.

My invention relates to means for reinforcing structures moreparticularly chutes commonly employed in conveying machinery and inwhich a belt or other moving device is utilized to carry grain andmaterial of various kinds from one place to another. My inventionrelates particularly to the proper bracing of the structure to stiffenit and to offset any tendency to bend or give under strain.

Referring to the drawings in which similar numerals indicate identicalparts Figure 1 is a side elevation of a structure showing my improvedbracing.

Fig. 2 is a section on the line 22 of Fig. 1 looking in the directionindicated by the arrow.

Fig. 3 is an enlarged detail showing the ends of adjoining sections ofthe structure and illustrating the manner of connecting them together,with ends of the braces secured thereto. V

Fig' 4. is a sectional detail on the line 14L of Fig. 1.

Fig. 5 is a detail section of the brace connection to the lower part ofone of the frames.

Fig. 6 is a longitudinal detail section of Fig. 5, and

Fig. 7 is a detail section of the brace connection to the posts.

The type of structure shown is composed of superimposed troughs l and 2built of sections held together by metallic posts 3, formed preferablyof angle steel, and frames -i made preferably of channel bars and bentto extend beneath the trough 2 and up both sidesof the troughs 1 and 2to which they are securely riveted. The frames 4 are preferahly locatedcentrally of the sections and have secured to them. on the sides of thetroughs 2, two-way castings 5 which project laterally from each side ofthe frames 4. The posts 3 are located at each end of the sections and onopposite sides thereof. and. as stated previously, are made preferablyof angle steel so that while one side of the angle is riveted to thetroughs 1 and 2, the

remaining side projectsat a right angle therefrom, the posts 3 being sosituated that as the sections are assembled to form the trough theprojecting sides of the posts 3, on the ends of the sections, arebrought into contact and rigidly secured together by suitable bolts.

Adjacent the tops of the posts 3 of each section are secured to theprojecting sides of the posts 3 castings 6, the same bolts beingutilized that hold the posts 3 together. Preferably integral with eachcasting is an arm 7 provided on its inner side with lugs 8. Braces 9made preferably of channel bars are riveted to the arms 7, the lugs 8extending within the channel and the rivets passing through the lugs 8and the posts 3. The braces 9 extend diagonally from the arms 7 downwardto the two-way castings 5 to which they are rigidly connected bysuitable rivets, the latter passing through the castings 5 and thebraces 9; the two-way castings 5 are provided with lugs or projections10 which fi snugly in the channel of the braces 9, and lugs ll form partof the castings 5 and are adapted to fit in the channels of the frame 4.To add to the strength of the connections of the braces 9 with thecastings 5 and 6, the latter are provided with flanges 12 which overlapthe sides of the braces 9 as shown in Figs. 5 and 6.

By the construction just described the greatest amount of strength isdeveloped to withstand any strain or tendency to buckle. Connecting thebraces to the posts 3 and the frames 4: the pull of the braces whenunder stress is borne by the posts 3 and frames 4. rather than by thetroughs 1 and 2, adding materially to the rigidity and durability of thestructure. \Vhile l have shown a structure composed of superimposedtroughs, i do not limit myself to this construction as my improvedmethod of bracing is equally effective when applied to structuresconsisting of one trough only.

What I claim isl. A chute having a plurality of posts secured thereto,each post comprising two parts of angle steel having one side of eachsecured to the chute and the rcimiining sides secured together toproject laterally from the chute, frames secured to the clnd'c h to theframes adjacent the bottoms thereof and extending diagonally upward 0nopposite sides of the frames, lugs on said castings to project in thechannel of the. frames, castings secured on opposite sides of the upperend of the lateral extensions of the posts and extending diagonallydownward, channel steel braces extending between the castings on theposts and frames and secured thereto, and lugs on the castings to fitwithin the channel of the braces.

3. A chute comprising a plurality of sections connected together byposts on opposite sides of the point of connection, each post consistingof a portion of angle steel secured to its respective section and havingone side projecting outwardly and adapted to contact with and be securedto the similar side of an angle portion on the adjacent section, acasting ad acent the upper end of each angle steel portion and securedthereon by bolts holding opposing portions together, each casting havingan arm pro ecting d1- agonally downward, a frame mounted on each sectionintermediate the end thereof, castings secured to said frame adjacentthe lower side of the chute and on opposite sides thereof, and bracesextending between the posts and frames and secured to the castingsthereon.

In testimony whereof I afiix my signature in presence of two witnesses.
